Multiple Home Assistant servers

Hi, it is possible to connet multiple HA servers?
I am behind firewall so I create HA server on public IP outside my home network and I send all data over MQTT. BUt with this configuration I am not able to use most of HA extensions.
So, is here some way, how to have 2 HA servers (one on public IP and second behind firewall in local network) with sharing data?
Thank you

The only options are either MQTT Eventstream or Statestream.

Thank you for your answer. So when I have some plugin in HA so first time I need to “publish” this data over MQTT to can use MQTT Eventstream.
Hmm, not so simply.
Thank you

Both will automatically publish either events (Eventstream) or states (Statestream) for the other HA server (or servers) to use. No “plugin” is required.

EDIT

MQTT statestream may also help you
